2 Claims.

The invention'relates to bed springs comprising spaced rows of verticalcoiled springs of which in a double bedthere are usually ninelongitudinal rows. Applicant has had much trouble in sleepingcomfortably in a double bed with another occupant much heavier than heis and an object of the invention is to provide means for simultaneouslyadjusting the tension of all of the vertical coiled springs related toany desired longitudinal area of the bed spring. Another object is toprovide such means having a common operating shaft operable from theside of the bed without removal of the bed spring therefrom.

The invention consists in the novel construction and combinations ofparts as hereinafter set forth in the claims.

In the accompanying drawings,

Figure 1 is a section on the line |-l, Figure 2.

Figure 2 is a bottom plan view of the invention as applied, parts beingbroken away.

Figure 3 is a detail section on the line 3-3, Figure 1, on a largerscale, parts being broken away.

Figure 4 is a detail section on the line 4-4, Figure 3.

Figure 5 is a detail perspective view of the detachable crank for theoperating shafts, one of said operating shafts being shown, partlybroken away.

In these drawings, the bed spring is shown as comprising a horizontalrectangular bottom frame I having spaced transverse bars 2 connectingthe side rails thereof; a horizontal rectangular top frame 4; avertically yieldable platform to 5 having spring connections 6 with theside and end rails of said top frame I, and a plurality of spacedlongitudinal rows of vertical coiled springs 3 located between saidplatform top and the transverse bars 2 of said bottom frame, saidsprings bearing at their upper ends against said platform top 5, all ofwhich is known construction.

The top rectangular frame 4 of the bed spring and the platform top areboth supported upon said coiled springs 3. This platform top may consistof a. plurality of longitudinal and transverse spaced bands 5 crossingone another at right angles.

Means are provided for simultaneously adjusting the tension of all ofthe vertical coiled springs 3 related to any desired longitudinal areaof the bed spring comprising a longitudinal bar 1 underlying eachlongitudinal row of said springs and to which the lower ends of aidsprings are connected by engaging perforations thereof and meanscomprising a plurality of sets of worm gearing supported upon thetransverse bars: 2 of said bottom frame and having a common operatingshaft for vertically adjusting each longitudinal bar 1. j j

The worm wheel 9 of each set of worm gearing i provided with a centralthreaded aperture with which a threaded standard 8 is engaged, saidstandard at its upper end engaging the longi tudinal bar 1. All of theworms II of the plurality of sets of worm gearing for verticallyadjusting each longitudinal bar I are provided with a common operatingshaft l0 journaled in the end rails of said bottom frame I As shown, aset of worm gearing is provided beneath each vertical coiled spring 3 ofthe bed spring. It is obvious that the longitudinal bar I underlyingeach longitudinal row of the vertical coiled springs 3 is capable ofbeing vertically adjusted by the threaded standards 8 related to alesser number of sets of worm gearing, one set of worm gearing locatedat each end and one set of worm gearing located in the middle of andbelow each longitudinal bar being sufficient.

A detachable crank 14 may be used for engagement with the squared ends[5 of any one or' more of the operating shafts [0.

Any suitable means may be provided to limit the adjustment of thevertical coiled springs 3 toward said platform top 5 and to preventsidesway.

In order to facilitate the use of the operating crank M for rotatablyadjusting the shafts [0, any suitable means may be used for raising thefoot end portion of a mattress used upon the bed spring and upholdingsaid foot end portion of the mattress out of way while the operatingcrank I4 is being used. The invention is subject to modifications comingwithin the scope of the claims.

I claim:

1. In a bed spring having a horizontal rectangular bottom frame providedwith spaced transverse bars connecting the side rails thereof, ahorizontal rectangular top frame, a vertically yieldable platform tophaving spring connections with said top frame, and a plurality of spacedlongitudinal rows of vertical coiled springs located between saidplatform top and said transverse bars of the bottom frame and hearing attheir upper ends against said platform top; means for simultaneouslyadjusting the tension of all of the vertical coiled springs related toany desired longitudinal area of the bed spring comprising alongitudinal bar underlying each longitudinal row of said springs and towhich the lower ends of said springs are connected, and means comprisinga plurality of sets of worm gearing supported upon said transverse barsof the bottom frame and having a common operating shaft for verticallyadjusting each longitudinal bar.

2. In bed spring having a horizontal rectangular bottom frame providedwith spaced transverse bars connecting the side rails thereof, ahorizontal rectangular top frame, a vertically yieldable platform tophaving spring connections with said top frame, and a plurality of spacedlongitudinal rows of ertical coiled springs located between saidplatform top and said transverse bars of the bottom frame and bearing attheir upper ends against said platform top; means for simultaneouslyadjusting the tension of all of the vertical coiled springs related toany desired longitudinal area of the bed spring comprising alongitudinal bar underlying each longitudinal row of said springs and towhich the lower ends of said springs are connected, and means comprisinga plurality of sets of worm gearing supported upon said transverse barsof the bottom frame for vertically adjusting each longitudinal bar, theworm wheel of each of said sets having a central threaded aperture, anda 4 threaded standard engaging said aperture, said standard at its upperend engaging said longitudinal bar, all of the worms of said pluralityof sets of worm gearing for vertically adjusting each longitudinal barhaving a common operating shaft.
